SPECIFICATION forming part of Letters'Patent No. 283,264,dated August 14, 1883.

` Application ledMarch 16, 1883. (No model.) l

To all lwhom it may concern:

Be it knownthat I, VILLIAM S. MELLAED, of Darien, in the county of McIntosh and State of Georgia," haveinvented a new and useful Improvement in Rice-Field Trunks and Gates, of which the following is a full, clear,

and exact description, reference beinghad to the annexed drawings, forming part of this specification.` i

This invention relates to watergates through which ricefields are flooded and drained in ,the process of irrigating the soil; and the in* vention consists ofthe novel construction `hereinafter described and claimed.` A 1' v In the drawings, Figure l is a cross-section of a levee, showing my invention in section v on line ma of Fig. 2; and Fig.`2 is a section of the invention on line 1/ y of Fig. l.

A indicates a levee, under and through which is located the trunk B for the passage of tide-Water at A into an adjoining rice-field `at B. i At the upper part of the trunk, prefera-bly at the center of the levee, is an upright chamber, C, 'which communicates with the `passage through the trunk, and in `which is `iitted a vertically-movable gate, D, adapted to closethe said passage when let down.`

`The gate is provided with a standard, E, projecting above the top of the levee, which is provided with recesses F, in which the end of a lever may be inserted for prizing up the gate, and by means of a series of perforations,

G, in the standard, and apin,` H', adapted to be placedin oneofuthe perforations and supported on crossebars l, the gate may be held in any raised position desired. When the tide- `Waterhas flooded` the `rice-field through the open passage, andthe gate is then let down, the

` water may be allowed to drain oft` gradually which, being light, may be easily raised by 5o hand, and which is adaptedto be supported in a raised position `by means of Va pin in the manner ofthe standard E.

The gate D is fittedA to slide loosely between the guides N N, which leaves sufiicient space for the water to rise up betweenthe gate and its guides at the side of the gate next to the body of water bearing against the same.

When the tide is at a level higher than it is desirable that the iield should be ilooded, .the 6o `pressure of the` tide against the closed gate will force the latter against its guides at the opposite side and allow the water to pass up at the nearest side of the'gate into the chamber C to the height of the tide without, and

the weight of thiswaterin the chamber C, resting on top of the gate, or in its chamber J, will hold the gate down against the action of the tide, thus formingatight joint and prey In 7o venting too great a flooding of the field. thesame mannen-if the field is to be flooded to a height reaching above the top of the'gate, leakage of the gate will be prevented by the water entering the chamber C to the level of that in the eld and forming a `tight joint in the manner above described.

y NVhat I claim is- 1. The combination of the trunk having the upright water-receiving chamber, communieating with the passage th rough the trunk, and 8o the gate litted in and adapted to be moved vertically in said chamber, and having a hinged i part adapted to open the passage through the trunk when the gate is down, substantially as i shown and described, and for the purpose y specified.

2. The combination of the trunk, the gate having an opening therein provided with a r i hinged valve, and a vertically-movable slide adapted to iit down behind the valve to hold 9o i the latter in a closed position', substantially as shown and described, and for the purpose specified.
